These rules are
designed to
allow students to get the maximum benefit for their time and
money
spent.
The physical attendance of lectures is not required but strongly
recommended.
If you happen to be late, enter class, do not apologize, quietly
take
your seat
and start working. If you need to leave, do so also as quietly
as
possible, do
not ask permission.
Do not talk in class even in a low voice since it is
disruptive
(asking
a fellow student a brief question is admissible, but should be
kept to
the
minimum). Do not hesitate to interrupt the lecturer with any
questions
or
comment, since it is beneficial for the class. (Do not assume
that your
question is too trivial to ask -- it may well be not so trivial.
Many
students
may have a similar problem. No questions and comments in class
will
affect your
grades in any way.)
SYLLABUS
Description
Nano-optics
deals
with optical phenomena and spectroscopy on the nanoscale,
i.e., in the
regions of space whose size is much smaller than light
wavelength. While an electromagnetic
wave cannot be localized in regions with the sizes
significantly smaller than
half wavelength, nano-optics is based on electric
fields oscillating at
optical frequency. As optical interactions with matter and
spectroscopy are
concerned, such local optical fields, in most cases, produce
the same type of
responses as electromagnetic waves. Elementary excitations
that are carriers of
energy and coherence in nanooptics are surface plasmons
(SPs). These
excitations exist at surfaces of metals whose dielectric
functions are negative.
The SPs are purely electric excitations that can and do
localize on the
nanoscale creating highly concentrated and resonantly
enhanced local electric
optical fields. These local fields cause a wealth of
gigantically enhanced
optical phenomena of which the surface enhanced Raman
scattering (SERS) is the
most studied and widely known. This course will encompass
the fundamental
properties and applications of the surface plasmonics at the
nanoscale. It will
include coherent effects associated with phase memory of the
SPs, in particular,
coherent control of nanooptical phenomena. Nonlinear
processes, for instance,
generation of harmonics and two-photon excitation by
nanoscale fields will also
be covered. Ultrafast (femtosecond and attosecond) phenomena
are within the
scope of this course. We will also include quantum phenomena
associated with SPs
as quantum quasiparticles, such as quantum generation,
amplification and
quantum fluctuations. Along with fundamental properties of
SPs, we will
consider the many applications of nanoplasmonics, in
particular, detection of
ultrasmall amounts of chemical and biological compounds,
scanning near-field
optical microscopes (NSOMs or SNOMs), and nanolithography.
